Specification of Letters Patent.
Application filed October 19, 1912. Serial No. 726,597.
To all whom it may-concern:
Be it known that I, FREDERICK W. FRANKE, a subject of the Emperor of Germany,'residing at Jamaica, in the county of Queens and State of New York, have invented certain new and useful Improvements in Removable Valve-Insulation Cas ings, of whichthe following is a full, clear, and exact-description.
This invention relates to improvements i valve and flange covering, and one of the objects of the invention. is to construct such a covering that it may be readily and quickly applied to'a valve or flange located in a pipe or lineof pipe used forheating, refrigerating, or for other purposes, and may be readily and quickly removed without disturbing or destroying the adjoining cover. 1
Another object of the invention is to construct such a casing that'it will effectively prevent radiation of either heat or cold in the valve or flange.
Another object of the invention is to construct such a casing at small cost.
Other objects will appear from the hereinafter description.
The inventionwill be clearly understood from the following description taken in connection with the accompanying drawings, which-form a part of this specification.
Referring to the drawings, in which the same reference character indicates the same part in the several views, Figure 1 is a side elevation of the invention applied to a valve located in-a line ofpipe. Fig. 2 is an end view of the casing, the two members of which. it is preferably madebeing shown slightly separated. Fig. 3 is a side eleva' tion of Fig.- 2; Fig. 4 is a view in section of the casing applied to a valve; Fig. 5 is a sectional view of the casing applied to flanges in a line of pipe; Fig. 6 is a side elevation of the same lookin in the direction of the arrow in Fig. 5; Flg. 7 is a side elevation of a modified construction 'of the casing; and Fig. 8 is an end view of the same.
The casing is preferably formed of two separable parts, which can be quickly and readily fastened together around a pipe or flange, or removed therefrom.
' Referring specifically to FigsQl to 4 inclusive, the part marked A on the drawing represents one end of a pipe and B the adjacent end of another pipe. C is a globe valve'to .Which the said ends of the pipe are attached. D is an asbestos covering around the pipe A, and E is an asbestos covering around the'end of the pipe B. The insulated casing which forms, this invention is marked F. It consists of two halves, 20

and 21, which when put together form a substantial cylindrical part, F, which surrounds the body of the valve; and two end members, 22 and 23, which have openings 24 and 25, through which the ends of the pipes A and B project into the chambers between said members when the casing is in place. The upper half 20 of the cylindrical member F is'provided with or formed into a dome, F which fits over the cover, 0, and surrounds the stem 0 of the valve, the upper end of the dome being provided with an opening, P, to receive the valve stem. The ends 22 and 23 are provided with outwardly extending flanges, 26 and 27, which are secured. to the ends of the cylindrical member, F, by riveting, or otherwise, and which form pockets 28 and 29 to receive the ends of the as bestos coverings, D and E, surrounding respectively the ends of the pipes A and B. The longitudinal edges of one of the halves 20 or 21 of the cylindrical member F, as here shown the lower one, may be offset at 28 and 29 to receive the respective longitudinal members of the upper half of said member to form a seat and tight joint between the said two halves. of the casing may be secured together by any suitable means. As illustrated, this means consists of tongues secured to the upper half 20, and which fit into keepers 31 stamped out of the lower half 21. The
The two parts thereof are collars or rings; 55- and 56,
"members 31, the free ends of latter half may be provided with one valve being removed to permit this half to be fitted around the valve, and after it s fittedthehandwheel is placed in position. The asbestos-may be placed in the upper half of the casing, either before or after the said casing is put in position. i The two halves of the casing are heldin position by the tongues the said tongues being turned or ,bent over to hold the said parts-securely together. When the casing is to be removed for packing the valves or joints, or forany other purpose,
- thevalve can be quickly and easily got at by removing the handwheel C straightening out the tongues 30, and liftingthe up-- per half off of the valve. The lower half can then be removed. It is apparent that the valve can be got at quickly and readily, without disturbing the asbestos covering} D and-E, and by'this improved casing an 'eiiicient and economical packing is provided forthe valve itself.
..In-Figs. 5 and 6 I have shown the casing flange by the reference characters 40 and constructed and adapted to fit around the flanges J, secured to the end of the pipes A and B, and anelbow L. I have indi-v cated the two halves of the casing for the 41. In this construction the ends 42 and 43 of the casing are provided with inturned flanges 46 and 47, instead of outturned, as in the construction shown in the preceding figures, the pockets, for the asbestos covering surrounding the pipe" A B and the elbow L, being marked respectively l8 and 4:9. The two halvesof this particular casing are-secured togetherby tongues 30 and corresponding members 3 1, as in the preceding construction. I y
In Figs. 7 and-'8 I have shown a slightly modified construction. In this construction the two halves of the casing are marked 50 and 51 respectively, and the .ends of these 1 two "halves are ginturnedl to form the flanges 52' and-53, leaving the openings 54 and 55 for the end of 'the' pipe secured to the said flanges 52 and 532 On the outside which have inturned fianges 57 --and '58, which are securedf to- -the .flanges '52 and 58,jwhich are securedto the flanges 52 and 53,- just-referred to: *These collars with the .inturned flanges form mg, and by which any leakage in the 'valve' 30 passing through the or provide pockets 59 and 60, to receive the asbestos packing surrounding the ends of the pipe which passes through'the openings 5& and 55 in this casing. The two halves of the casing are preferably held together by tongues 61 on the upper half of the casing, which ex- 1 tends into the members 62 in the lower half of the casing.
In the construction shown .by Figs..5 to 8, inclusive, certain of the longitudinal edges of thehalves'forming the casings may be offsetto receive the adjacent longitudinal edges of the other half, as described in reference to the construction shown by the first five figures of the drawing.
While I have described the parts as be ing fastened together by rivets, it is apparent that they may be fastened togetherby brazing, welding, or' in any other suitable manner, and in each instance the two halves of the casing of either construction may be held together and fastened around the pipe in any suitable manner.
Of course, in some cases the asbestos filling or packing insidethe casing may he means may be provided inside of each half of the casing to suitably space the a casing from the valve or flange which it surrounds.
dispensed with; and in-this case suitable The casing is preferably made out of sheet metal, so that the parts may be quickly and cheaply stamped or formed to shape,
and the parts quickly and economically put together.
Having described my' invention, what I claim as-newand. desire to secure'by Let ters Patent is I 1. A casing of the class described formed of a pair of sections divided from each other longitudinally approximately along the median line of the casing, each. of said sections comprising an outer wall and in' ternal solid partitions, said partitions'hav ing recesses to receive the pipe and being spaced from each other and set back from the extremities of the casing, whereby outwardly open pockets at the ends of the easing and a single chamber between said pockets are provided, the chamber being adapted to'receive coupling packing, said chamber being independent of and separate from the adjoining pockets which latter are adapted to receive pipe covering, said casing also havingmeans-for securing its sections together, said means being adapted to permit the casing to be readily opened along theline of separation of the sections.
2. A casing of the class described, convi 5 sisting of a cylindrical member and end members secured to the cylindrical member and spaced inwardly from its ends to form the outwardly opening pockets, and a central separate and independent chamber, each end member being'provided'with an 1 0 opening therein for the pipe, the casing insulating material and the pockets to re- 10 being divided approximately along its meceive the pipe covering.
